What medicine can I use for urinary incontinence caused by spinal injury?

Good morning, I have a question about the drug omnic ocas, because when taking this drug there is no improvement and exactly I am often unable to hold urine, I have been taking it for 2 years because it was then that I broke my spine in 3 places and had difficulty urinating, fortunately I walk but there was also a slight damage to the spinal cord, what drug I could take so as not to get wet and at the same time the power to urinate freely. Please help. Yours sincerely.
